本数据集聚焦北美家燕羽毛颜色的数量遗传学研究，通过全同胞/半同胞设计及纵向分析，探究遗传与早期发育环境（包括母本表型、巢环境）对黑色素羽毛颜色的影响，揭示其作为性信号的进化意义，包含2个关联文件。 论文“Quantitative genetics of plumage color: lifetime effects of early nest environment on a colorful sexual signal”
Postcopulatory sexual selection is an important force in the evolution of reproductive traits, including sperm morphology. In birds, sperm morphology is known to be highly heritable and largely condit
Rapid diversification of sexual traits is frequently attributed to sexual selection, though explicit tests of this hypothesis remain limited. Spermatozoa exhibit remarkable variability in size and sha
